-BLANK BAR FOR TIE-PLATES.

SPECIFICATION forming part of Letters Patent No. 465,260, dated December15, 1891.

Application filed lune 10, 1891.

To all whom it may concern:

Be it known that LWILLIAM GOLDIE, a citizen of the United States,residing at Bay City, 1n the county of Bay and State of Michigan, haveinvented certain new and useful Improvements in Blank Bars forTie-Plates, of whlclrthe following is a specification, reference belnghad therein to the accompanying drawings.

My invention relates to improvements in manufacturing tie-plates, andpertains to the manufacture of the tie-plate or rail-chair descrlbed andclaimed in Letters Patent issued to me April 29, 1890, No. 426,530; andmy invention consists in the form and construction of a rolled metalblank or bar for formingthe tie-plate by severing each separate platefrom the end thereof.

The object of the invention is to provide a cheap and expeditious meansof manufacturlng the tie-plate described'and claimed in Letters PatentNo. 426,530, hereinbefore mentioned.

My invention is illustrated in the accompanying drawings, in whichsimilar letters of reference indicate like parts throughout the severalviews.

Figure l represents a plan view of the blank bar for forming thetie-plate. Fig. 2 isaview showing the bottom or under side of the blank`par. Fig. 3 isa longitudinal section of Fig.'l. rig. 4 is a top or planview of a plate after 1t is severed from the blank bar. Fig. 5 is a Viewshowing the bottom or underside of the plate. Fig. Gis a section ofFig..4, taken at a'. Fig. 7 is a transverse section of the rail witlhthe plate in position as supporting the rai a represents a thin plate ofrolled metal of a width transversely to conform to the transversedimension of the plate or chair to be made, and upon the upper side ofthis plate is arranged a longitudinal rib b, located upon one side ofthe transverse centerof the plate,

while upon the under or opposite side of the plate and at or near theedges thereof are provided longitudinal ribs c, preferably arranged withtheir outstanding edges brought to an angle or made sharp, and d is aseries of transverse ribs, of a V form, raised outwardly from the underside ofthe plate a and be- SerialNo. 395,792.

tween the ribs c,with which they are arranged to intersect. The distancebetween the V edges of the transverse ribs d is arranged to coincidewith the longitudinal dimension of the chair to be made. This plate isformed by passing the metal between suitable rolls in the usual manner,the rolls having their peripheries arranged to form the longitudinal andtransverse ribs, as described, and the tie-plates or chairs are thencompleted by severing with suitable shearing devices the plate a throughthe longitudinal center of each transverse V-rib d, as shown by thedotted lines y y, and then, by means of suitable punches, the plates orchairs are completed by forming openings e and f for the spikes, theopening e being cut through the longitudinal rib b, so that when thechair is in position for holding the rail, as shown in Fig. 7, the outerlateral edges of the base-ange of the rail will rest against the innerside of the rib b, While the head portion of the spike q, driven throughthe opening e and into the tie, will reach over the flange and retainthe rail upon the chair, while the spike n, passed through the openingf, firmly retains the opposite edge of t-he .rail-flange in position. A

It will be noticed that by severing the sections from the bar, as beforedescribed, each section or chair will be provided on the edges of itsunder side with a downwardly-projecting continuous rim similar in formand construction to the rail-chair described in the aforesaid LettersPatent, and which when the chair is in position between the rail and tiewill form a firm and solid bearing for the rail and Water to the tiebeneath the rail by the continuous rib being impressed or embedded intothe surface of the tie, and at the same time provide a cheap and easymeans of binding the inner spike to the outer spike, so as to moreeectually resist a lateral or crowding strain upon the rail. It willalso be seen that by rolling the bar or plate to the form described andthen severing the several chairsections therefrom provides a cheap andexpeditious process for forming the chairs or tie-plate, as by rollingthe plate in this manner the raised ribs are formed without extra costor labor, except the formation of the IOO rolls, so that a superior formof rail-support is provided at a comparatively small cost and expense.

Having described my invention, what I claimas new, and desire to secureby Letters Patent, is-

1. A blank bar for the manufacture of railroad chairs or tie-plates,consisting of a bar of rolled metal having on the transverse center ofone side a raised longitudinal rib and provided on the edges of itsopposite side With raised longitudinal ribs and with a series of raisedtransverse ribs at intervals intersecting the said longitudinal ribs,for the purpose set forth, substantially as described.

2. A rolled metal bar for the manufacture of tie-plates or rail-chairs,provided on one side of the transverse center of its upper side-
